Parton picture for the strongly coupled SYM plasma
نویسنده
چکیده
Deep inelastic scattering off the strongly coupledN = 4 supersymmetric Yang– Mills plasma at finite temperature can be computed within the AdS/CFT correspondence, with results which are suggestive of a parton picture for the plasma. Via successive branchings, essentially all partons cascade down to very small values of the longitudinal momentum fraction x and to transverse momenta smaller than the saturation momentum Qs ∼ T/x. This scale Qs controls the plasma interactions with a hard probe, in particular, the jet energy loss and its transverse momentum broadening.

Jet evolution in the N = 4 SYM plasma at strong coupling
Within the framework of the AdS/CFT correspondence, we study the time evolution of an energetic R–current propagating through a finite temperature, strongly coupled, N = 4 SYM plasma and propose a physical picture for our results. In this picture, the current splits into a pair of massless partons, which then evolve via successive branchings, in such a way that energy is quasi–democratically di...
متن کاملWilson loops in heavy ion collisions and their calculation in AdS / CFT
Expectation values of Wilson loops define the nonperturbative properties of the hot medium produced in heavy ion collisions that arise in the analysis of both radiative parton energy loss and quarkonium suppression. We use the AdS/CFT correspondence to calculate the expectation values of such Wilson loops in the strongly coupled plasma ofN = 4 super Yang-Mills (SYM) theory, allowing for the pos...
متن کاملPartons and jets in a strongly–coupled plasma from AdS/CFT∗
We give a pedagogical review of recent progress towards understanding the response of a strongly coupled plasma at finite temperature to a hard probe. The plasma is that of the N = 4 supersymmetric Yang–Mills theory and the hard probe is a virtual photon, or, more precisely, an R–current. Via the gauge/gravity duality, the problem of the current interacting with the plasma is mapped onto the gr...
متن کاملShockwaves and deep inelastic scattering within the gauge/gravity duality
Within the gauge/gravity correspondence, we discuss the general formulation of the shockwave metric which is dual to a ‘nucleus’ described by the strongly–coupled N = 4 SYM theory in the limit where the number of colors Nc is arbitrarily large. We emphasize that the ‘nucleus’ must possess N2 c degrees of freedom per unit volume, so like a finite–temperature plasma, in order for a supergravity d...
متن کاملOn jet quenching parameters in strongly coupled non-conformal gauge theories
Recently Liu, Rajagopal and Wiedemann (LRW) [1] proposed a first principle, nonperturbative quantum field theoretic definition of “jet quenching parameter” q̂ used in models of medium-induced radiative parton energy loss in nucleus-nucleus collisions at RHIC. Relating q̂ to a short-distance behavior of a certain light-like Wilson loop, they used gauge theory-string theory correspondence to evalua...
